Many times, I've found myself on the internet trying to find out different methods of pattern manipulation to best fit my costumes.
So, when I got into FIT, I was blessed with a whole mountain of information and resources. One of these resources is my patternmaking book.
Patternmaking for Fashion Design 4th Ed. By Helen Joseph-Armstrong.
Now, I took the time to scan and upload these so please don't take without my permission to put on other sites. For personal reference, feel free to use this.

For more please e-mail me with what you want and I'll see if I have a tutorial on it.
